Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The embodiment provides an gasbag winding and unwinding devices for inflatable landing stage, carries out the automatic receipts of gasbag through control hydraulic cylinder and puts, avoids artifical manual work, is applicable to the inconvenient occasion that carries out the manual work and receive and release the gasbag.

As shown in fig. 1, the airbag housing apparatus includes: hydraulic cylinder 1, round pin axle 2, ears 3, hydro-cylinder axle 4, monaural 5, gasbag fixing device 7 and run from opposite directions door plant 8, wherein run from opposite directions door plant 8 includes two side door plants that can open relatively.

The air bag 13 is fixed below the inflatable trestle side bridge section 9 by the air bag fixing device 7, as shown in figure 4. The airbag fixing device 7 includes: four sets of connecting fasteners consisting of connecting plates 10, metal clamping plates 11 and fixing bolts 12; the air bag 13 adopts a four-side fixed connection mode, the folding and unfolding direction of the air bag 13 is longitudinal, and two lateral sides of the air bag 13 are respectively provided with a side door plate; one longitudinal end of the air bag 13 is fixedly connected with the bottom surface of the side bridge section 9 through two sets of connecting fasteners, and the two transverse sides of the air bag are fixedly connected with the side door plates of the split door plates 8 arranged on the corresponding sides through one set of connecting fasteners respectively. Taking the fixed connection of the airbag 13 and the bottom surface of the side bridge section 9 as an example: the metal clamping plate 11 is of a plate-shaped structure, one end of the metal clamping plate 11 is provided with a groove for placing the connecting plate 10 (fixedly connected with the air bag 13, namely an external connection interface of the air bag), and the connecting area of the connecting part can be increased by arranging the metal clamping plate 11, so that reliable connection is ensured; one side that metal cardboard 11 placed connecting plate 10 is laminated with side bridge festival 9 bottom, and the opposite side is laminated with gasbag 13, then connects gradually gasbag 13, metal cardboard 11, connecting plate and side bridge festival 9 through fixing bolt 12, and then to gasbag 13 fixed connection in side bridge festival 9 bottom. Since the inflated airbag 13 is pressed by water in the water, the entire end surface of the airbag 13 facing the bottom surface of the bridge segment 9 is closely attached to the bottom surface of the bridge segment 9.

The split door plate 8 comprises two side door plates which are respectively arranged on two transverse sides of the air bag 13, and each side door plate is driven by two hydraulic oil cylinders 1, so that the split door plate 8 is opened or closed. When the split door panel 8 is in a horizontal closing state, the air bag 13 is in a recovery state, the split door panel 8 closes a longitudinal expansion channel of the air bag 13, namely a closed surface opposite to the bottom surface of the side bridge section 9 is formed when the split door panel 8 is closed, and the air bag 13 is positioned in a closed space formed by the side bridge section 9 and the split door panel 8; when the split door panel 8 is opened to be in a vertical state, the longitudinal deployment passage of the airbag 13 is opened, and the airbag 13 can complete the deployment action.

The front end and the rear end of each side door plate are respectively provided with a hydraulic oil cylinder 1 (the transverse direction of the air bag 13 is the left-right direction, and the longitudinal direction is the up-down direction), and as shown in fig. 3, the two hydraulic oil cylinders 1 are controlled to synchronously move, so that the opening or closing of the side door plate 8 is realized. Two side door plates of the split door plate 8 are connected with the side bridge sections 9 in the same way; each hydraulic oil cylinder 1 is connected with the side bridge section 9 and the corresponding side door plate in the same way; take the connection of a side door panel and a hydraulic cylinder on the side door panel as an example: the bottom of the side bridge section 9 is provided with two lugs 3, a single lug 5 on the side door plate is connected with one support lug of the two lugs 3 through a pin shaft 2 (a connecting point A), and the side door plate can rotate around the pin shaft 2, so that the side door plate can be switched between a horizontal state and a vertical state; the cylinder body end of the hydraulic cylinder 1 is connected with the other support lug of the double lug 3 through the cylinder shaft 4 (the order is a connection point B), the axis of the cylinder shaft 4 is parallel to the axis of the pin shaft 2, the piston end of the hydraulic cylinder 1 is fixedly connected with the side door plate on the corresponding side (the order is a connection point C), the connection point A, the connection point B and the connection point C are not on the same straight line, the double lugs 3, the side door plate (namely the single lug 5 on the side door plate) and the hydraulic cylinder 1 form a crank link mechanism, when the hydraulic cylinder 1 acts, namely a piston rod of the hydraulic cylinder extends or retracts, the side door plate is driven to rotate around the pin shaft 2 connected with the double lugs 3, the opening or closing of the side door plate 8 is realized, and in the rotating process of the side door plate.

The air bag 13 is exhausted by a blower, and the cloth of the air bag 13 is gathered towards the gas outflow direction after the air bag 13 is exhausted due to the extrusion force of water; be equipped with a plurality of discharge valves on gasbag 13, consequently utricule cloth can regular gathering at each gas vent, because gasbag 13 is fixed with side bridge festival 9 and run from opposite directions door plant 8 again, the effectual concentrated pile of having avoided all cloths together to accomplish gasbag 13 and retrieve the action.

The working principle of the air bag deploying and retracting device is as follows:

initially, the airbag 13 is in a recovery state, and the two side door panels are in a horizontal state, namely, the two side door panels 8 are in a closed state; when the airbag 13 needs to be deployed, the four hydraulic oil cylinders 1 are controlled to synchronously act, piston rods of the four hydraulic oil cylinders are extended to push the two side door plates to rotate clockwise around the corresponding pin shafts 2, the built-in displacement sensors 6 of the hydraulic oil cylinders 1 detect the strokes of the pistons of the hydraulic oil cylinders 1, when the strokes of the pistons reach set values, stroke in-place signals are sent out, the hydraulic oil cylinders 1 are controlled to stop acting, at the moment, the two side door plates are opened to be in a vertical state, and therefore the airbag deployment action is completed. Conversely, when the air bag 13 needs to be recovered, the air outlet valve on the air bag 13 and the blower for air outlet are opened first to exhaust the air bag 13; and simultaneously controlling the four hydraulic oil cylinders 1 to synchronously act to enable piston rods of the four hydraulic oil cylinders to contract to drive the two side door plates to rotate anticlockwise around the corresponding pin shafts 2, extruding the air bags 13 and exhausting the auxiliary air bags 13 in the closing process of the side door plates 8, detecting the stroke of the pistons of the hydraulic oil cylinders 1 by the built-in displacement sensors 6 of the hydraulic oil cylinders 1, sending stroke in-place signals when the stroke of the pistons reaches a set value, controlling the hydraulic oil cylinders 1 to stop acting, and closing the side door plates 8 when the two side door plates are in a horizontal state to finish the recovery of the air bags 13.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
